Calystegia sepium
Hedge false bindweed
Synonym(s):
Family: Convolvulaceae (Morning-Glory Family)
Duration and Habit: Perennial Vine
Photographer: Robert H. Mohlenbrock

Description
Perennial from rhizomes, trailing or climbing vine to 10 feet long, with distinct triangular leaves. Found throughout the eastern United States to the Great Plains, and also in the upper northwestern states. Flowers have two leafy bracts at the base, leaves are triangular in outline with 'dog-ears'.
Native Lookalikes: Currently no information available here yet, or there are no native Texas species that could be confused with Hedge false bindweed.
Ecological Threat: Competes with the native plants for water, nutrients, and light. Can climb and smother native vegetation. More research has been focused on field bindweed than hedge bindweed due to its impact on agriculture.
Biology & Spread: Impermeable seeds can last 20 to 50 years in a soil seedbank. Long-range dispersal of seeds is likely because seeds can remain viable in the digestive tract of birds for as long as 144 hours. One plant may produce up to 600 seeds per year, of which 90% may be viable. Its flowers last for just one day and are insect-pollinated by honeybees, bumblebees, and lepidoptera.

Native Alternatives
This weed is often mistaken for invasive Field Bindweed (Convolvulus arvensis). However, field bindweed leaves are smaller, with a more rounded apex and bases that are pointed or rounded, but not cut off squarely across the top as in hedge bindweed.
Management
Bindweed is incredibly difficult to eradicate due to its extensive underground system of roots and rhizomes. If the home gardener can continuously pull any new sprouts, the rhizomes will lose strength eventually. But this requires consistent weekly effort, without a break, and usually for more than one season. Also, because it twines tightly around nearby plants, removing the bindweed vines can be difficult without damaging the host plants. It is possible to cut the weed where it meets the ground, but the stems of the dead bindweed plant will still be visible after they dry and brown.
